We will see how amenability of a group assists one when working with its
group ring, and also helps in working with group rings in general. We
will introduce a notion of the Newton polytope of a matrix, and see how
it is relevant in the study of fibreings of 3-manifolds, and in general
in the theory of Bieri--Neumann--Strebel invariants.
